ARNOLD MOETTELI, OF OBERWIN'IERTHUR, SWITZERLAND, ASSIGNOR TO DRY QUENCH- IN G EQUIPMENT CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF DELA- WARE COKE COOLING APPARATUS Application filed June 30, 1928, Serial No. 289,382, and in Switzerland February 29, 1928. i

This invention relates to improvements in apparatus for dry cooling hot coke.

A primary object of my invention is to provide coke cooling apparatus in which the walls of the coke container are protected in a simple manner and in which the heat ab sorbed by the protecting means is taken advantage of to perform work such, for eX- ample, as the generation of steam.

Another object of my invention is to provide protecting means for the walls of the coke container of coke cooling apparatus which is adapted to absorb heat from cooling gases employed in the apparatus and also to absorb heat radiated by the coke.

A further object of my invention is the provision of a water walled cooling chamber for coke cooling apparatus of the type in which the coke is introduced into the cooling chamber in a. container and is cooled by passing a cooling gas through the coke.

A more specific object of my invention is to provide an improved arrangement and means for circulating cooling gases in apparatus of the type herein set forth.

Still another object resides in associating a steam boiler with a coke cooling chamber into which the coke is introduced in a container in a simple and eflective manner, the arrangement being such that among other advantages, the life of the container and cooling chamber is greatly increased.

How the foregoing, together with such other objects and advantages as may hereinafter appear, or are incident to my invention, are realized is illustrated in preferred form in the accompanying drawings, wherein Figure 1 is a sectional elevation of coke cooling apparatus constructed in accordance with my invention, the section being taken substantially on the line 1-1 of Figure 2.

Figure 2 is a cross section of the apparatus taken substantially on the line 22 of Figure 1, with certain parts appearing in elevation.

In the drawings a transportable coke container is illustrated at a, which container is introduced into a cooling chamber 0 adapted to be closed by a door 0', the container being introduced preferably in the manner disclosed in my copending application Serial No. 234,626, filed November 21, 1927 i. e., the container is run into the cooling chamber on suitable tracks a. The container at is provided with a perforated built-in structure .7) through which gas is introduced for cooling the coke, as will now appear.

Thecooling gases are led under pressure to the container 0 by means of thecfan d, the V mlet or suction side of which is connected to a the conduit 6 leading from the lower part of the cooling chamber, and the outlet or pressure side of which is connected to the pressure line fleading to the container a. The pres sure line f is so located with relation to the perforated structure 6 of the container that it is automatically connected, as indicated at f, to such structure when the container is introduced into the cooling chamber. The direction of the gases and the path thereof is clearly indicated by the arrows, it being noted that the gases are drawn from the lower portion of the chamber, passed through the coke in the container by pressure of the fan, and then on leaving the container pass downwardly to the lower port-ion of the chamber.

In order to protect the walls of the coke container from high temperatures and thereby increase its life, I have provided a heat exchanger in association therewith. The heat exchanger comprises, in general, tubes it through which acooling medium is cir'cu lated, the tubes being located adjacent the walls of the cooling chamber and in the space between said walls and the walls of the coke container whereby they serve to keep the Walls of the container and chamber cool.

Baflling his preferably associated with the tubes h for causing the gases to pass through the space between the tubes at their upper portion tov the rear of the tubes and thence downwardly to the lower portion of the cooling chamber. Thus the gases pass in a cycle fromthe lower part of the chamthe gases passing over them, but also to heat radiated from the coke.

The tubes k may be connected to conveniently arranged boiler drums, and in the drawings I have illustrated a lower drum is located in the lowerportionot the cooling chamber 0 and annpperdruini located in the upper portion of the chamber, so that a vertical tube boiler is formed, the row of tubes h of which are spaced sufliciently apart to permit of the introduction of the coke container (1, as will be clear from the draw ings.

I claim:

1. Apparatus for dry cooling hot coke and the like comprising, in combination, a cooling chamber, a coke container located in said chamber and spaced from the walls thereof, heat exchanging means located in the spaces between the side walls of the cooling chamber and the coke container, and means for.

circulating cooling gases in said chamber in a cycle from a portion of thechamber removed from the coke container through the container, over the heat exchanging means and back to said removed portion of the chamber, the circulating means including ablower, means for leading gas from the removed portion of the chamber to the blower, a gas discharge nozzle in the coke container,

' means forleading gas from the blower to the nozzle, and baiile means providing a passageway for the gases from above the container over the heat exchanging means and to the removed portion of the chamber.

2. Apparatus for dry cooling hot coke and the like comprising, in combination, a cooling chamber: an open topped coke container adapted to be transported into and out of said cooling chamber; said cooling chamber having an entrance opening for the introduction of the coke container and means for closing said opening; evaporating means in said chamber for protecting sa1d coke container against overheating; perforated gas inlet means in the lower portion of the container for introducing cooling gases into said container; a gas blower line having its inlet located within the lower portion of the cooling chamber and having its outlet in said cooling chamber and adapted for delivery of gas through said perforated gas inlet means when said coke'container is in said cooling chamber; and gas passages establishing communication between the upper and lower portions of said cooling chamber; said evaporatin g means being located in said passages.

3. Apparatus for dry cooling hot coke and the like, comprising, in combination, a cooling chamber; an open topped coke container adapted to be transported into and out of said cooling chamber; said cooling chamber having an entrance opening for the introduction of the coke container and means for closing said opening; evaporating means in said chamber for protecting said coke container against overheating; means for passing cooling gases through the container when said coke container is in said cooling chamber and over the evaporating means, the last mentioned means including a blower line having an inlet; section communicating with the cooling chamber at the lower portion thereof, and adischarge section in said cooling chamber, a blower connecting said sections for causing circulation from the inlet section to the discharge section, and a discharge nozzle located in the coke container, said nozzle being adapted to be connected to the discharge section and adapted to discharge gases into the container when said coke container is in said cooling chamber; and bafile means arranged to provide passages for the gases from the In testimony whereof I have hereuntosigned my name.
